BITCOIN SAVINGS FAQ
When is the daily interest credited?
We calculate the interest on your account balance daily and credit it at a random time every day. If the interest would be credited at a fixed time everyday, people would be able to game the system by depositing before the credit time and then withdrawing after they receive their interest. To avoid this, the daily interest is calculated and credited at a random time everyday.
How do you make money to pay us interest?
When you hold money in your FreeBitco.in account, we split it into 3 parts - the first part is used to cover user withdrawals, the second part is used to bankroll our MULTIPLY BTC game and the third part is used to expand our bitcoin mining operation (which is currently 9.065Petahashes or 0.009% of the total hashpower of the bitcoin network). We make a profit and assume the full risks of our businesses and in return for you saving your money with us, we give you a risk-free fixed rate of return.
Below, we have signed a message using our bitcoin address that is used to collect payments from our bitcoin mining operation. This message can be verified on any bitcoin client or here to provide proof that we actually mine bitcoin.
PROOF OF MINING
BITCOIN ADDRESS
MESSAGE
SIGNATURE
Please do not send any deposits to our mining address. To deposit bitcoins to your account, please use the deposit button at the top of the page.
Is there a lock-in period or minimum investment period before I start earning interest?
No! You start earning interest from the first day itself. There is no lock-in period, you can withdraw your bitcoins anytime you wish by using the WITHDRAW button at the top of the page. We always keep enough reserves to satisfy all withdrawals.
Can I earn referral commissions on interest earned by my referrals?
Yes! We pay you a 25% commission on any interest earned by your referrals. If your referral gets 100 satoshi in interest for a day, you will get 25 satoshi credited to your account.
Will the interest rate be fixed forever or can it change?
We may change the interest rate in the future if circumstances change. However, we shall communicate all rate changes at least 30 days in advance via the website and our twitter account (https://twitter.com/freebitco).
How can I trust you with my money?
We have been in business since 2013 and are one of the most popular bitcoin websites (check our Alexa rank here). Our users have deposited thousands of bitcoins and we have paid out tens of thousands of bitcoins over the years. We have also published proof of our mining operation above which can be used to monitor the mining payments we receive. We would recommend that you start saving small amounts first until we have earned your trust after which you can save larger amounts with us if you feel comfortable doing so.
How can I keep my account secure to protect my savings?
It is extremely important that you secure your account if you decide to hold a significant balance with us. Change your account password to a strong random one with atleast 15 characters and never ever share that password with anyone or re-use it with another website or service. Then activate 2-factor authentication and write down the secret key on a piece of paper to back it up since we do not reset 2-factor authentication under any circumstances (you lose your phone, reset it etc.). Both of these can be done by accessing the PROFILE page from the menu above.
How do you store bitcoins securely?
We use a combination of hot wallets, hardware wallets (Trezor) and BIP38 encrypted paper wallets to store bitcoins. At no time do we keep more than 5% of our total bitcoins in the hot wallet which is used for making payouts. The hardware wallet is used as a \"warm\" wallet and bitcoins are transferred from it to the hot wallet as required. Our paper wallets serve as our \"cold\" storage with the wallets generated on an air-gapped computer running Tails OS. Our hardware and paper wallets are also secured against physical theft as the hardware wallet requires a pin code and encryption password to access and the private keys in the paper wallet are encrypted which means that the coins in the wallet cannot be accessed without having both the private key and the encryption password. We also keep physical copies of the cold storage wallets at multiple locations.
Can I opt-out from receiving interest on my account balance?
Sure, you can do so under the DISABLE INTEREST option in the PROFILE page.

Bet on the latest events against other FreeBitco.in users and win a share of the prize pool if you pick the winner!
Early bets have a higher weight and will get a bigger share of the prize pool!
The Time Weight Multiplier is an additional factor added to our betting events to incentivize early bets by assigning them a higher weight than later bets.
The Time Weight Multiplier starts at 100 for each event and goes down as time passes, eventually reaching 0 when the event ends.
The weight of each bet is assigned as (Bet Amount)*(100%+(Time Weight Multiplier)%). So, a bet made with Time Weight Multiplier of 99x will have a weight of 199% and a bet made with Time Weight Multiplier of 30x will have a weight of 130%.
In the example above, the bet with Time Weight Multiplier of 99x will win 60% (199/(199+130)) of the prize pool and the bet with Time Weight Multiplier of 30x will win 40% (130/(199+130)) of the prize pool.
So the quicker you make your bet, the higher share of the prize pool you can win!

PROVABLY FAIR LOTTERY
SERVER SEED HASH FOR CURRENT ROUND
This lottery is provably fair. What that means is that there is no way the site can cheat you by picking a lottery winner who we favour. All winners are picked randomly and the method for picking the winners is described below.
At the beginning of each round, we generate a server seed for that round and show you the SHA256 hash of this seed.
When a lottery round has concluded, we make a list of all user id's and their lottery tickets and sort it in ascending order of the user id's.
We then use this list to assign ticket numbers for all tickets. For example if user id 1 has 10 tickets and user id 2 has 20 tickets, then user id 1 will have ticket numbers 0 to 9 and user id 2 will have ticket numbers from 10 to 29. This is done for all users.
Then the list containing the user id's, tickets held by each user and their ticket numbers is published in a text file. This file also contains the total number of tickets issued in the round and the server seed for that round.
A MD5 hash of this text file is calculated.
Then the current bitcoin block number is recorded and a block number that is 12 blocks into the future is decided on. The block hash of this future block is used as a \"client seed\" ie. a seed that we are not aware of when the list in step 4 has been published.
Then a tweet is made via our twitter account (https://twitter.com/freebitco) containing the link to the file generated in step 4, the MD5 hash of the file and the future bitcoin block number as determined in step 6. Since tweets cannot be edited, only deleted, this will provide a timestamp for when the list in step 4 was made, which can be compared to check that the bitcoin block determined in step 6 is in the future ie. we do not know the block hash of this block when the list is generated.
The winning ticket numbers will be calculated as described below:
A string (STRING1) is created - \"[SERVER SEED]:[BLOCK HASH]:[WINNING POSITION]\".
The SHA256 hash of STRING1 is calculated and the first 8 characters of this hash are taken (STRING2).
STRING2 is converted to a decimal which gives us a number between 0 and 4,294,967,295 (NUM1).
NUM1 is then multiplied by the (total number of tickets minus 1) and divided by 4,294,967,295 to get a number (NUM2) between 0 and the total number of tickets less 1.
NUM2 is then rounded off to the nearest whole number which is the winning ticket number.
HOW IS THE SYSTEM FAIR?
The system described above that is used for picking the winners is provably fair because it has multiple safeguards in place to ensure that winners are picked randomly and fairly.
We provide a SHA256 hash of the server seed when a lottery round starts. If we change the server seed at any time, the SHA256 hash of the new seed will not match the hash we provided earlier. After a round has ended and we provide the server seed that will be used to pick winners, the hash of the seed we provide can be checked against the hash we provided originally and both should match.
We use a future bitcoin block hash as the \"client seed\" ie. a seed that we do not know of. All bitcoin block hashes are unique and nobody knows what the block hash of a future block will be until the block has been mined.
We use twitter to publish the future bitcoin block number, the list of users and their ticket numbers and the MD5 hash of the user list. It provides a timestamp to check if the block hash that we use is indeed in the future. Since tweets cannot be edited, only deleted - if we delete the tweet after the future block has been mined and publish a new one, it would be easy to catch us cheating by comparing the timestamp of the tweet and that of the bitcoin block. The timestamp of the tweet should always be lesser than the time timestamp of the bitcoin block whose hash is used as the client seed.
We provide a MD5 hash of the text file containing the list of users and their ticket numbers. If even a single character in the text file is changed after the MD5 hash in the tweet is published, the MD5 hash of the edited file will not match the MD5 hash provided in the tweet.
This game is provably fair. What that means is that there is no way the site can cheat you by picking a number that is in our favour.
The way this works is that each roll is calculated using 3 parameters - the server seed, client seed and nonce. Out of these, we show you the client seed and nonce that will be used for your next roll along with a SHA256 hash of the server seed. You can also change the client seed if you wish. The server seed is the only part that is kept a secret until after the roll.
Then after you roll, under the section titled PREVIOUS ROLL DETAILS, we show you the server seed that was used and you can verify that this was the same server seed that we said we were going to use before the roll by checking if the SHA256 hash of this seed matches the SHA256 hash that we showed you before the roll.To know exactly how we calculate the rolls, read the section below titled How are rolls calculated?
After you roll, you can also click the link above named CLICK HERE TO VERIFY YOUR ROLLS to verify your roll using our javascript based roll verifier which uses the same seeds to re-calculate the roll right in your browser without any external communication.
How are rolls calculated?
Two strings are created : STRING1 = \"[NONCE]:[SERVER SEED]:[NONCE]\" STRING2 = \"[NONCE]:[CLIENT SEED]:[NONCE]\" For your last roll : STRING1 = \"[NONCE]:[SERVER SEED]:[NONCE]\" STRING2 = \"[NONCE]:[CLIENT SEED]:[NONCE]\"
Then HMAC-SHA512 is used to hash STRING1 with STRING2 as the secret key, giving us a 128 character hex string.
The first 8 characters of the hex string are taken and converted to a decimal.
This decimal is then divided by 429496.7295 and rounded off to the nearest whole number.
This whole number is used as your roll, with the maximum possible value being 10,000.
You can track the visits and signups that you are getting from multiple traffic sources by adding the tag parameter (&tag) to your referral URL.
For example, to track the visits and signups from Source 1, add &tag=source1 to your referral URL and then promote that URL (http://freebitco.in/?r=7831930&tag=source1) and you will be able to see the signups and visits from that source by selecting source1 in the dropdown menu below.
You can create as many tags as you want on the fly and they can be a string of upto 150 characters comprising of small and large case letters and numbers, excluding the number 0.
Why does the amount of Bitcoins that you can win, keep changing?
The amount of bitcoins that you can win with FREE BTC depends on the current bitcoin price and the biggest prize is fixed at US$200 and the other prizes in proportion to it. So, when the price of a bitcoin goes down, the reward amount calculated in bitcoins goes up and the other way round is also true. So, regardless of the current bitcoin price, you have a fair chance of winning US$200 in bitcoins on each roll.

BONUS YOU WISH TO CLAIM
BONUS TERMS
The MULTIPLY BTC bonus works in the following manner:
When you claim a bonus, an equivalent amount is deducted from your account balance and the amount+bonus is transferred to a bonus account. For example, if you claim a bonus of 0.001 BTC, an additional 0.001 BTC will be deducted from your account balance and your bonus account will have a balance of 0.002 BTC.
The balance in your bonus account needs to be wagered 25 times in the MULTIPLY BTC game before it is credited to your main balance. In the above example, you need to wager 0.05 (0.002* 25 ) BTC before the balance in your bonus account is transferred to your main account.
The maximum wagering requirements that you can fulfill in a single bet cannot exceed 10% of the original amount of your bonus account. Following the example above, if you make a bet of less than or equal to 0.0002, the full amount will be counted towards your wagering requirements but for bets over 0.0002, only a maximum of 0.0002 will be counted towards your wagering requirements. However, 100% of all jackpot bets will be counted towards fulfilling your wagering requirements.
If you have any balance in your bonus account, it will be used first for all wagers that you make and the winnings will be added to your bonus account. If you make a wager larger than the amount in your bonus account, the wager will be taken first from your bonus account (until it is 0) and the remaining will be taken from your main account and the winnings will be added to your bonus account.
When you complete the wagering requirements for a bonus, the full balance of your bonus account will automatically be added to your main account (within a few minutes) and can be withdrawn to your wallet immediately.
Any amount spent on playing for the jackpot will also count towards fulfilling your bonus wager requirements.
You can only have 1 bonus active at any time.
Active bonuses do not have any expiry date and will last forever until the wagering requirements are met.
Once claimed, a bonus cannot be cancelled until the wagering requirements have been fulfilled.

This lottery is provably fair. What that means is that there is no way the site can cheat you by picking a lottery winner who we favour. All winners are picked randomly and the method for picking the winners is described below.
At the beginning of each round, we generate a server seed for that round and show you the SHA256 hash of this seed.
When a lottery round has concluded, we make a list of all user id's and their lottery tickets and sort it in ascending order of the user id's.
We then use this list to assign ticket numbers for all tickets. For example if user id 1 has 10 tickets and user id 2 has 20 tickets, then user id 1 will have ticket numbers 0 to 9 and user id 2 will have ticket numbers from 10 to 29. This is done for all users.
Then the list containing the user id's, tickets held by each user and their ticket numbers is published in a text file. This file also contains the total number of tickets issued in the round and the server seed for that round.
A MD5 hash of this text file is calculated.
Then the current bitcoin block number is recorded and a block number that is 12 blocks into the future is decided on. The block hash of this future block is used as a \"client seed\" ie. a seed that we are not aware of when the list in step 4 has been published.
Then a tweet is made via our twitter account (https://twitter.com/freebitco) containing the link to the file generated in step 4, the MD5 hash of the file and the future bitcoin block number as determined in step 6. Since tweets cannot be edited, only deleted, this will provide a timestamp for when the list in step 4 was made, which can be compared to check that the bitcoin block determined in step 6 is in the future ie. we do not know the block hash of this block when the list is generated.
The winning ticket numbers will be calculated as described below:
A string (STRING1) is created - \"[SERVER SEED]:[BLOCK HASH]:[WINNING POSITION]\".
The SHA256 hash of STRING1 is calculated and the first 8 characters of this hash are taken (STRING2).
STRING2 is converted to a decimal which gives us a number between 0 and 4,294,967,295 (NUM1).
NUM1 is then multiplied by the (total number of tickets minus 1) and divided by 4,294,967,295 to get a number (NUM2) between 0 and the total number of tickets less 1.
NUM2 is then rounded off to the nearest whole number which is the winning ticket number.
The [WINNING POSITION] starts at 1 and is increased by 1 for picking the 10 winners. The user having the ticket with the lowest [WINNING POSITION] wins the first prize and so on.
If a user wins more than 1 prize, the number is discarded and [WINNING POSITION] is increased by 1 and the calculations are run again to pick a new user. This is to ensure that a user cannot win more than 1 prize in a round.
HOW IS THE SYSTEM FAIR?
The system described above that is used for picking the winners is provably fair because it has multiple safeguards in place to ensure that winners are picked randomly and fairly.
We provide a SHA256 hash of the server seed when a lottery round starts. If we change the server seed at any time, the SHA256 hash of the new seed will not match the hash we provided earlier. After a round has ended and we provide the server seed that will be used to pick winners, the hash of the seed we provide can be checked against the hash we provided originally and both should match.
We use a future bitcoin block hash as the \"client seed\" ie. a seed that we do not know of. All bitcoin block hashes are unique and nobody knows what the block hash of a future block will be until the block has been mined.
We use twitter to publish the future bitcoin block number, the list of users and their ticket numbers and the MD5 hash of the user list. It provides a timestamp to check if the block hash that we use is indeed in the future. Since tweets cannot be edited, only deleted - if we delete the tweet after the future block has been mined and publish a new one, it would be easy to catch us cheating by comparing the timestamp of the tweet and that of the bitcoin block. The timestamp of the tweet should always be lesser than the time timestamp of the bitcoin block whose hash is used as the client seed.
We provide a MD5 hash of the text file containing the list of users and their ticket numbers. If even a single character in the text file is changed after the MD5 hash in the tweet is published, the MD5 hash of the edited file will not match the MD5 hash provided in the tweet.
If you had funds with us during the recent Bitcoin hard-fork, we have credited you with extra Bitcoin Cash (BCC) coins for each Bitcoin that you had with us.
You can exchange your Bitcoin Cash (BCC) that was credited to you directly into Bitcoin at a rate of 0.145 BTC/BCC. When you exchange, the extra Bitcoins will be added to your account balance and can be withdrawn instantly.
The BCC that you have received is in addition to the BTC that you had with us and is an extra amount which can be exchanged to increase your BTC holdings by 14.5% by simply clicking a button!
Bitcoin has 2 hard forks planned in the near future - \"Bitcoin Gold\" and \"Bitcoin Segwit 2x\". As we have done with the \"Bitcoin Cash\" hard fork in the past, we shall support withdrawals of all hard fork coins as long as they are viable - ie. have wallet support, a working blockchain and straightforward redemption policies.
We shall distribute Bitcoin Gold to your accounts shortly after they release a wallet and they have a working blockchain. You can monitor their progress at https://bitcoingold.org/blog/
The Bitcoin Segwit 2x hard fork seems to have been suspended so it will have no impact. If it is revived at some point in the future, we shall distribute those coins to your account as well.
If you had funds with us during the recent Bitcoin hard-fork, we have credited you with extra Bitcoin Gold (BTG) coins for each Bitcoin that you had with us.
You can exchange your Bitcoin Gold (BTG) that was credited to you directly into Bitcoin at a rate of 0.019 BTC/BTG. When you exchange, the extra Bitcoins will be added to your account balance and can be withdrawn instantly.
The BTG that you have received is in addition to the BTC that you had with us and is an extra amount which can be exchanged to increase your BTC holdings by 1.9% by simply clicking a button!
The option to withdraw your BTG will also be available in a few days.
